Adding metal band to wood are ivory is a common technique, used to
keep dagger handles from splitting. It can also be used to add band
of different metal around metal base.
Use gold 18k or higher. 14k possible, but more difficult. Mark the
location of metal band on the piece. File tiny grooves all around,
marking off the area where the band would go. Prepare the band with
internal dimension exactly matching the external dimension of the
area. This is the most critical step. Exactly means exactly. You
should not be able simply to slide the band in place. The band is
driven in place by special punch, which is copper pipe of exactly
When the band is in place, carefully file the external edges to
taper the ends of the band. To secure band in place, simply turn the
edges down with a pusher, in a manner of setting a cabochon gemstone.
If everything done correctly, very little compression of the metal
would be required.
